Description

technical field [0001] The invention relates to a system in the technical field of electric vehicle power battery management, in particular to an electric vehicle power battery management system based on an ARM microprocessor. Background technique [0002] With the development and progress of the automobile industry, people have higher and higher requirements on the power, economy, safety and emission of automobiles. New energy vehicles have gradually become the development direction of the current and future period. Due to its own particularity, without a reasonable and reliable management system, power batteries are prone to problems such as overcharging, overdischarging, and high temperature. It will affect the safety of the power battery itself and the safety of personnel and vehicles. A reliable battery management system is of great significance to prevent battery overcharge and overdischarge, improve battery utilization, and extend battery life, especially for new ene...
